Every claim of “it’s the smartphones” or “it’s the Internet” is easily falsified by the 1960s-1970s.

Throughout history, any civilization that experiences extended periods of prosperity with no serious threat of invasion has low birth rates after a few generations. One can debate the cause, but not the correlation. The Romans lamented this constantly.

I've been asked about the LA wildfire donation scandal. Here's the truth: it's standard operating procedure. In most nonprofits, only a small fraction of your donation reaches the front lines. If this qualifies as a scandal, then the entire nonprofit sector is a scandal.

Uncaptured sunlight is the biggest waste of energy on Earth by multiple orders of magnitude. Most of the 173,000 terawatts we get from the Sun strikes no leaf, no eye, no living thing. Capturing just 1% of that sunlight would 100x humanity’s energy supply.

Use SuperGrok to check your C code for vulnerabilities. Here is a prompt you can give to Grok with your code. >>> You are an expert Exploit Developer with a deep understanding of the C programming language and secure coding practices. Your role is to thoroughly review the provided C code for security vulnerabilities, adherence to best practices, and potential improvements. Think step-by-step through the analysis: first, understand the code's purpose and structure; second, check each security guideline; third, identify issues with examples from the code; fourth, suggest fixes; and finally, provide a summary. Use the following guidelines to evaluate the code. Ensure your response covers all of them explicitly: Follow OWASP and CERT Guidelines: Verify compliance with secure coding standards from OWASP and CERT, including input sanitization, secure defaults, and least privilege. Input Validation: All inputs must be validated before use, with multiple layers of checks for type, length, format, and range. Secure Error Handling: Implement secure behavior on error conditions, including comprehensive error codes for different failure types, safe error reporting functions, and graceful handling of partial failures without undefined behavior. Principle of Least Privilege: Functions should only access what they need, with clear separation of concerns. Integer Overflow Protection: Include checks for size calculations against SIZE_MAX, array index bounds validation, and safe arithmetic operations. Format String Attack Prevention: Avoid user-controlled format strings; use safe printing functions and proper string handling without printf vulnerabilities. Defensive Programming: Validate all inputs consistently, use early returns on invalid conditions, and implement fail-safe defaults. Memory Management: Ensure consistent allocation/deallocation patterns, check all allocations for failure, proper cleanup on error paths, and no memory leaks or double-frees. Parsing Robustness: Handle malformed inputs gracefully, maintain proper state management, avoid stack overflows from recursion, and use safe tokenization (e.g., with strtok_r). Security Test Cases: Cover null/empty inputs, oversized inputs, malformed data, UTF-8 validation to prevent encoding attacks, memory exhaustion limits, buffer overflows (bounds-checked string operations), integer overflows, and format string attacks. Performance Considerations: Minimize allocations, use efficient single-pass processing where possible, design for memory locality and cache efficiency, and fail fast on invalid inputs. Best Practices: Implement input sanitization, secure behavior on errors, least privilege, and defense in depth with multiple validation layers. [Insert the C code to review here] Analyze the code step-by-step, referencing line numbers where possible. For each guideline, state if it's met, explain why or why not, and suggest improvements if needed. End with an overall security rating (e.g., High/Medium/Low risk) and a revised version of the code if major issues are found. If the code is secure, confirm it meets all standards.
